Barcelona will face their toughest assignment yet in their bid to maintain their 100% start to the La Liga season, as they travel to fellow unbeaten side Atletico Madrid .

The Catalans have been in irresistible form so far, winning all seven of their matches under new boss Ernesto Valverde with Lionel Messi banging in 11 goals and looking back to his very best.

They will be in unfamiliar territory on Saturday though as they visit the Wanda Metropolitano, Atletico's stunning new stadium, for the first time and Diego Simeone's men already look to be at home there having won both of their opening league matches there without conceding a goal.

Remarkably Barcelona haven't lost away to Atletico in the league since February 2010, and despite their formidable home record in recent years they will be confident of extending that unbeaten run.

Team news

Atletico Madrid

Former Chelsea left-back Filipe Luis and central defender Lucas Hernandez are both expected to be back for the clash against the table toppers having missed the goalless draw at Leganes with minor hamstring niggles.

Fellow defender Sime Vrsaljko has been out with a thigh injury, and is likely to miss out despite making good progress in recovering from the problem.

Diego Costa is unable to play until January after rejoining Atletico from Chelsea for £53 million, with recent evidence suggesting he has plenty of work to do to get up to speed before then.

Barcelona

Record £110 million signing Ousmane Dembele remains sidelined with a hamstring injury, and isn't expected to be back until at least the start of 2018 meaning former Everton man Gerard Deulofeu or Denis Suarez will start alongside Lionel Messi and Luis Suarez in the front three.

Rafinha continues to be sidelined with a long-term meniscus problem, and Arda Turan will not be fit to face his old club after bruising his metatarsal.

Ernesto Valverde has the rest of his squad to choose from, with Andres Iniesta set to play for the first time since signing a lifetime contract at the Nou Camp.
